Dry type transformer factoryIn relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point, it will affect the whole power circuitStolin,The selection shall be carried out according to the load characteristics of power. There are many types of power loads. Different dry-type transformers shall be used for different power loads. If the standard impulse level of power load is less than kV, class H dry-type transformers shall be used. If the standard impulse level of power load exceeds kV, epoxy resin adhesive shall be used to pour dry-type transformers.Before application, the sampling container shall be cleaned with vehicle gasoline,StolinLoss standard of dry type transformer, soapy water or other organic solvents (such as trisodium phosphate) except oil stains, and then washed with tap water until it is not alkaline, and the water can be evenly distributed from the bottle, and then cleaned with purified water for many times. The cleaned sampling container shall be dried in a ℃ drying oven. After refrigeration, the bottle cap shall be tightly closed and cannot be opened before application.Mentekab,After tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.There are many connection groups of dry-type transformers, and the selected structures and connections are also different. Then, pay attention to the following matters:The cycle time of power-off cleaning and inspection shall be determined according to the surrounding environment and load conditions, generally from half a year to once a year;Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core, and long-term scalding of iron core will lead to insulation aging.Which one is better,Sound, causing short circuit obstruction. If not handled properly, and then causes gas vibration noise most of it is scattered according to the building structure. This kind of low-frequency noise is scattered to the household house according to the house building, which is then scattered to the ears of consumers. Although the amount of noise is not very large, the dispersion spacing and adverse effects are very large.

When the screw of the through core extruder holding the iron core of the transformer is loose,StolinComprehensive protection of power transformer, there are screw cap parts left on the iron core, or small metal materials fall into the transformer, the transformer will send out & ldquo; Ding Ding Dang & rdquo; Or & ldquo; Call & hellip; Call & hellip& rdquo; Blowing sound and its & ldquo; Squeak, squeak & rdquo; It's like a magnet sucking a small washer, while the working voltage, current and temperature of the transformer are all normal. Such conditions generally do not endanger all normal operation of the transformer, and can be solved until power failure.Respect for customers,The first step of the whole wave process calculation is to calculate the basic parameters of the Internet such as inductance capacitance and resistor. The accuracy of those basic parameters does great harm to the calculation results of the whole wave process. For the inductance calculation, but there are many calculation methods.If the input of dry-type transformer is an alternating switching power supply the good model is the solid model of infinite transformer core column, because it is DC, add a circuit in the input power supply circuit to change it into a continuously changing voltage. In that way,StolinDry type test transformer, the alternating DC current can be obtained at the output end.Common problems of tap changer of power transformerStolin,Method and process of taking oil sample of power transformer& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by V megger, the resistance value exceeds m ohm bus.The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:
